NATIONAL FOREWORD

This Indian Standard which is identical with ISO 4162:1990 ‘Hexagon flange bolts — Small series’issued by the International Organization for Standardization ( ISO ) was adopted by the Bureau ofIndian Standards on the recommendations of the Bolts, Nuts and Fasteners Accessories SectionalCommittee and approval of the Medical Instruments, General and Production Engineering DivisionCouncil.

The text of ISO Standard has been approved as suitable for publication as an Indian Standard withoutdeviations. Certain terminology and conventions are, however, not identical to those used in IndianStandards. Attention is drawn especially to the following:

a) Wherever the words ‘International Standard’ appear, referring to this standard, they should beread as ‘Indian Standard’.

b) Comma ( , ) has been used as a decimal marker while in tndian Standards, the current practiceis to use a point ( ) as the decimal marker.

In this adopted standard, reference appears to certain International Standards for which Indian Standardsalso exist. The corresponding Indian Standards, which are to be substituted in their places are listedbelow along with their deg~ee of equivalence for the editions indicated:

As decided by the Committee additional requirements of packaging and BIS Certification Marking aregiven in National Annex A. These additional requirements are part of this standard.

For the purpose of deciding whether a particular requirement of this standard is complied with, the finalvalue, observed or calculated, expressing the result of a test or analysis, shall be rounded off inaccordance with IS 2 : 1960 !Rules for rounding off numerical values ( revised )’. The number ofsignificant places retained in the rounded off value should be the same as that of the specified value inthis standard.

Check on head and flange gauges

The head shall be gauged using two ring gauges, A and B, to demonstrate the coincidental acceptabilityof hexagon height,wrenching height, corner fill and width across corners.

Gauge A shall be placed over the head and shall seat on the flange.

Gauge B shall be placed on the top of the head normal to the bolt axis. The two gauges shall not be in contact.
